Filed: 1970-04-21
Abstract: 1300325 Carburetters SOC INDUSTRIELLE DE BREVETS ET D'ETUDES 21 April 1970 [21 April 1969] 18893/70 Heading F1B In a carburation device for an I.C. engine of a vehicle, comprising at least two carburetters each having a main fuel jetting system (not shown), an idling and slow-running fuel channel 6, 6a, Fig.1, and a throttle valve 2, 2a, a mixing channel 4 receiving fuel through pipe 13 and air through orifice 14, is communicated with passages 17, 17a leading to respective carburetters during those periods when the vehicle is decelerating with throttle valves 2, 2a closed and the engine is rotating at a speed in excess of, say, 1300 to 1400 r.p.m. During such periods the suction created downstream of the closed throttle valve 2 is sufficient to cause a diaphragm-actuated or, as shown, a bellows-actuated valve 28 to open and communicate the suction to diaphragm chamber 25 to thereby lift a rubber diaphragm 19 and allow mixture to flow from channel 4 to the passages 17, 17a and hence into carburetter tubes 1, 1a, The valve 28 may instead be actuated by an electromagnet (37), Fig.3 (not shown), energized by an electronic relay (36) adapted to measure engine speed, e.g. by counting the ignition pulses.

[Class 74 (ii)] [Also in Group XI] Blankets, pads, carpet underlays, clothing, &c. are composed of knitted fabric with a weft cord 3 incorporated therein during manufacture for use as an electrical heating device. The fabric may consist of independent warp chains 2 held in place by the weft 3. The heating element consists of comparatively low resistance wire 4 wound spirally on a core 5 of wool, cotton &c., and wrapped with varnished textile yarn 8. The wire may be enamelled and covered with silk &c. 7. The selvedge loops of the cord are subsequently bound with lengths of tape 10 stitched at 11, 12. Instead of a continuous weft, a number of warps may be incorporated in the fabric and subsequently joined at the ends. The cord is connected to twin wires 17, 18 of a lead 13 projecting into the pocket a and provided with a lamp holder adapter.

Title: Disazo dyestuffs containing sulphuric ester groups
IPC: C09B31/02
Filed: 1973-04-19
Abstract: 1380677 Disazo dyestuffs containing sulphuric ester groups BAYER AG 19 April 1973 [20 April 1972] 18993/73 Heading C4P Novel disazo dyestuffs have the formula wherein A is C 2-4  alkylene, D is a radical of a diazo component of the benzene or naphthalene series which is free of SO 3 H and CO 2 H groups, B is an SO 3 H- and CO 2 H-free 1,4-phenylene or 1,4-naphthylene radical, and K is an SO 3 H- and CO 2 H-free coupling component radical. They contain only one -O-A-O-SO 3 H group and this is bonded to a carbon atom of an aromaticcarbocyclic or aromatic-heterocyclic ring in B or K. They are prepared by conventional coupling methods using components which either already contain the -O-A-O-SO 3 H radical or which contain the -O-A-OH radical; in the latter case this radical is subsequently sulphated either in the monoazo dyestuffs first formed from diazotized DNH 2  compounds and appropriate anilines or naphthylamines, or in the final disazo dyestuffs formed from said monoazo dyestuffs and appropriate coupling components. In the first coupling component the amino group may be protected by a group R (R=-SO 3 H or -CH 2 SO 3 H) in which case this group must be split off before the second coupling  can be effected. Products containing a free phenolic OH group in K may subsequently be etherified by alkylation with, for example, a dialkyl sulphate, an alkyl halide, chloroacetonitrile, ethylene oxide or ethylenechlorohydrin. Intermediates of the formulae are isolated. The novel dyestuffs are used to dye nitrogencontaining fibre materials in yellow, orange, scarlet-red, bluish-tinged red and claret shades.

As shown, a halfsilvered mirror 9 is disposed between screen 8 and the view-finder and co-operates with a further mirror 12 to project the image on to surface 3. Figs. 2 and 3 (not shown) illustrate two other ways in which the image-converter, camera tube and view-finder may be disposed within the camera case. An iris diaphragm may be provided between the image-converter and surface 3. The image-converter may project an enlarged image in the view-finder and may also provide a marginal field of view. Suitable deflecting fields may be employed to shift the electronic image in the converter to permit the effective field of view of the camera to be changed without interfering with the camera scanning. The converter may be pulsed to enable transient or rapidly changing phenomena to be observed whilst still operating the camera tube under normal storage conditions. It is stated that the colour response of the sensitive surface of the camera tube and the screen of the image-converter may be matched to improve the signal-to-noise ratio.

Abstract: 638,436. Non-metal resistances; temperature variable resistances. WESTERN ELECTRIC CO., Inc. July 18, 1947, No. 19264. Convention date, May 17, 1939. [Class 37] Resistors possessing a negative temperature coefficient, for example thermistors, Figs. 1 and 2 (not shown), are made from a resistance material which comprises a compound of manganese oxide and an oxide of iron or nickel. Fig. 3 shows the relationship between specific resistance and atomic ratio of the metallic elements for a series of resistors made from different proportions of iron and manganese oxidescurve A-and different proportions of nickel and manganese oxides-curves B and C. If a mixture comprising finely divided oxides of iron and manganese, wherein the atomic ratio of the two metals Fe/Mn= 2.0 is heat treated at a temperature between 1000‹ C. and 1450‹ C., the compound manganese ferrite is formed and the specific resistance is a minimum. In curves B and C which are different due to different heat treatment, the minimum in specific resistance occurs between atomic ratios Mn/Ni=2.0 and 4.0 and corresponding to this minimum the product is a material in which a solid solution is formed between the compound nickel manganate and an excess oxide. It is stated that although in accordance with changes in heat treatment resistors of different specific resistances are produced, each will possess the same negative temperature coefficient. The Specification as open to inspection under Sect. 91 states that other combinations may be utilized, namely zinc and uranium or manganese and uranium or combinations selected from the oxides of aluminium magnesium, copper, zirconium, tin, chromium, cobalt, titanium and zinc. In the case of zinc and uranium or manganese and uranium it is stated that the minimum resistance for a specific heat treatment corresponds to an integral atomic ratio or nearly so, as in Fig. 3. This subject-matter does not appear in the Specification as accepted.
